Abstract
PURPOSE: To make it possible to store binary information, "1" and "0", by forming regions with high and low secondary-electron emission ratios on an information memory medium of a chalcogenite thin film.
CONSTITUTION: Onto support plate 2 of a glass plate, electrode layer 3 is provided and on which chalcogenite thin film 4 with excitation effect is formed by the irradiation of write electron beam 5, thereby constituting information memory medium 1. With electrode layer 3 grounded, accelerated beam 5 of 10 to 20KV from the thin film 4 side is made to scan on medium 1 and then, regions (secondary-electron emission ratio N of one region irradiated with beam 5 is shown by curve A, and ratio N of the other irradiated with no beam is by curve B) with high and low secondary emission ratios are fromed on medium utilizing that thin film 4 shows the excitation effect through the irradiation of beam 5, so that binary information, "1" and "0", will be stored.
